FAN ATTACHMENT FOR CHAIRS.

SPECIFICATION forming part of Letters Patent No. 421,206, dated February 11, 1890. Application led May 3, 1889. Serial No. 309,447. (No model.)

To all whom it may concern:

Be it known that I, ROBERT TAGGART, of Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Fan Attachments for Chairs; and I do hereby declare that the following is a full, clear, and exact description of thc invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to an improved fan attachment for chairs.

The object of the invention is to provide an improved fan attachment adapted for use upon chairs, cradles, dto., complete in all particulars, exceedingly cheap and simple in constructioincomposed of a minimum number of strong durable parts, and which is automatically operated to vibrate the fan by the rocking of the chair, cradle, &c.,to which the device is attached. These objects are accomplished by and my invention consists in cer tain novel features of construction and combinations of parts, more fully described hereinafter, and particularly pointed out in the claims.

Referring` to the accompanying drawings, Figure l is an elevation of the device, partly in longitudinal section. Fig. 2 is a detail view of the fan-clamp. FiO. 3 is a detail. Fig. et is a perspective view of a rockin gchair, showing the invention attached.

In the drawings, the reference-letter o. indicates a tubular casing adapted to be clamped in a vertical position to a chair and extend down almost to the licor and a suitable distance above the seat of the chair. This casing is provided with a clamp Z7, by which the casing is secured to the seat or arm of the chair, and this clamp is adjustably secured to the casing by means of the split ring having projecting ears and setscrew c, so that the clampV can be moved up or down and rigidly secured in position. At its lower end the casing is provided with a clamp d to engage the upper part of a rocker of the chair, and this clamp is adjustably mounted upon a horizontal arm c, adjustably secured to the casing by means of a split ring, projecting ears, and clamping-screw, the same as clamp Z), and as shown in Fig. 3. Thus the clamp d can be moved horizontally upon the arm or rod e, so that the casing can always be held in aperpendicular position when used upon chairs of different constructions. Upon its upper end the casing is provided with a hollow head or T-couplin g f, preferably having its top closed by a suitable ornament, and having a slde'opening g, in which a bushing or short pipe-section 71, is inserted to form a bearing. This head fis secured to the upper end of the casing to prevent longitudinal but allow rotary movement independent of the casing, preferably, by means of a pipe-section t', secured in the lower opening of the head f, and having a contracted portion extending down into the upper end of the casing, the shoulder formed by this contracted portion bearing on the upper edge of the casing, and the pipe having an annular peripheral groovej, receiving` the ends of one or more set-screws 7c, extending through the casing. An operating-rod l extends through the casing and at its upper end into the headf, and atits lower end is screwed into a plug m., extending beneath the casing. Said plug' is provided wit-h a rubber cap or base n to engage the iioor. A coiled spring o is located in the casing, constantly tending to hold the operating-rod to its limit of downward movement, and at its lower end the spring bears against plug m and at its upper end against a plug p, rigidly secured in the casing. By adjusting this plug m upon the end of the operatingrod the tension of the spring can be varied. The rubber base upon the lower end of said plug prevents injury to the floor or carpet.

A horizontal rock or fan shaftq extends at right angles from the casing and is adapted to extend horizontally over the chair. At its inner end this rock-shaft is journaled in the bushing 7L in the side opening g of the head on the upper end of the casing and provided on its inner end. within said head with a cranlrarin q', extending laterally and loosely secured to the upper end of the operating rod by means of the crank-pin r, so that when this rod is reciproca-ted the shaft is rocked.

The fan-holding devices consist of a split tube or sleeve S, embracing and adjustable the length of and around the 1'ocksliaft and roo having the pair of laterally-projecting ears t t provided with transverse registering openings, through which a tapered clamping-pin c extends, the smaller threaded end of which is provided with a thumb-nut a', while the opposite end of the pin is provided with an enlarged head having a transverse opening b and is split longitudinally, as shown. A rod c extends through said opening b and is provided with a socket or clamp upon its lower end to receive the fan-handle, said socket being formed by a longitudinally-split and externally-threaded enlargement at said end of the rod having a longitudinal opening d', having an external clamping-nut e to clamp the fan-handle in the socket or release the same. The rod is also provided with'a transverse opening f ,in which the fan-handle can be inserted, and wherein it can be clamped by the nut. It will thus be seen that the fan can be universally adjusted and clamped in any position, and that the pin c is drawn through the apertures of the ears t t by the single nut a, thereby clamping the sleeve s to the shaft and the rod c in the pin o. By this arrangement the fan can be raised and lowered and adjusted to any inclination or horizontally the length of the rock-shaft.

It should be observed that the exterior of the fan-clamp and the interior of the nut,

therefore, are tapered, as shown, so that when on the upper end of said casing, a horizontal rock-shaft at one end journaled and extending into said head, a rod in the casing to rock the shaft, and a fan-holder carried by the shaft, substantially as described. y

2. In a fan attachment, the combination of a lrock-,shaft and means, substantially as set forth, to rock the same, with a split sleeve on the shaft having projecting ears with registering openings, a tapered clamp-pin extending through said openings, having its large end split longitudinally and provided with a clamping-opening, and means, substantially as described, at the smaller end of said pin to draw the same through said ears, and thereby clamp the sleeve on the shaft and Contact said clamping-opening, substantially as described.

3. In a fan attachment, the combination of a tubular casing, the horizontal rock-shaft and its fan-holder, a reciprocable rod extending through and below the casing and connected with the shaft and threaded at its lower end, and an adjustable plug on the lower end of the rod having a soft base, a stationary stop in the casing, and a coiled spring embracing the rod and bearing against said stop and plug, as set forth.

4. In a fan attachment, the combination, with a tubular fan-carrying casing, of a clamp vertically adjustable on the Casing to engage the arm or seat of a chair,a lateral rod secured to and vertically adjustable on the lower portion of the casing, and a clamp ad-
